Don't understand....
Her family arent poor?
So on what logic do you need to marry him, to be able to live a stable and quiet life?
Sure that the heroine never gets jealous?
Never seen a drama in your precious life?

I think it is because if she married any other man, they'd expect her to be a proper wife. The emperor, however, literally just wants her to sit there with the title and that's all that is necessary. I do wonder how she will be able to completely avoid political schemes though. People might use her for schemes such as blaming her for their killing attempts on the heroine etc.
But we do expect love.
Sry not sry :3
